GEORGE A. LEIGHTON, OF MANCHESTER, NEW HAMPSHIRE.

KNITTING- MACHINE.

SPECIFIGATION- forming part of Letters Patent No. 272,560, dated February 20, 1883. Application filed April 3, 1882. (No model.)

To all whom it may concern Be it known that I. GEORGE A. LEIGHTON, of Manchester, county of Hillsborough, State of NewHampshire,haveinvented an Improvement in Knitting-Machines, of which the following description, in connection with the accompanying drawings, is a specification.

This invention relates to circular-knitting machines having plate and cylinder needles adapted to produce different kinds of ribbed work, as may be desired, and to knit a commencing course suitable for a finish for the knitted fabric:

' The object of the invention is to enable the changes in position of the different cams which actuate the plate and cylinder needles, and also the needle-cylinder, to be controlled and effected automatically by a pattern-surface when it is desired to change from one to another kind of knitting.

This invention is an improvement on the machine described in my application No. 15,02 filed August 9, 1880, to which reference may be had. The machine herein described, embodying my invention, contains a series of plate and cylinder needles. The plate-needles are operated by a series of cams and cam-switches having connected slide-rods, the positions of which are changed, according to the requirements of thefabric, through certain Jacquard cams, to be described, moved by semicircular slides, provided with legs actuated by the projections of the Jacquard chain or pattern-surface. The camsandcamswitchesforcontrollingthemovement of the cylinder'needles and for shogging the needle-cylinder for the production of the commencing course to serve for the finished end of the fabric, or to produce an ornamental border or band, are also controlled as to their times of movement in like manner by the jacquard. The jacquard serves to arrest the knitting devices just before the needle-cylinder is to be shogged, for changes in knitting,

I and having determined the shogging of the needle-cylinder, the jacquard again eii'ects the starting of the knitting devices. Instead of employing an independent thread for asepa- ;rating course between two articles-such, for instance, as cuffs-or when part of onejacket is to be separated from another, or to separate two different varieties of knitting, I employ one of the threads of which the fabric is com- I posed, manipulating it by knitting only on the plate-needles, the cylinder-needles then acting as sinkers, making preferably a single course of plain web, the stitches of which will be subsequently cut.

My invention consists in the several mechanical organizations hereinafter described, and particularly pointed outin the claims atthe end of this specification, whereby I am enabled to represented, automatic in its operations, or, rather, make the movements of the two sets of needles andtheiractuatingmechanism dependent upon a pattern-surface provided with pins or independently adjustable and changeable prot-nberances.

Figure l is a top view of my improved ma.- chine, the bobbins and stands being removed. Fig. 2 is a rear side view of the machine, some of the parts being broken out to more clearly show other parts, the Jacquard chain being partially shown in dotted lines. In Fig. 2 the cam-plate has been moved half a revolution beyond the position in Fig. 1. Fig. 3 is a partial vertical section of the machine, on the line of shaft E, the latter being, however, in elevation, the cam-plate having been turned snflisaid shaft.

The bed A of the machine is mounted on suitable legs, A, and connected with the said bed and legs are suitable brackets and bearings to support the working parts to be described. The counter-shaft B has on it a fast pulley, B, and a loose pulley, B which receive at proper times the power-belt B controlled by the forked arm ofa belt-shipper, B adapted to be liberated automaticallyto shift the belt 13 w the loose pulley WhrIlcVel the yarn is exhausted from the bobbins or the work runs ofithe needles of the machine. The belt-shipper, near its handle, has a pin, B

which is engaged, asin Fig. 43, by a catch of a pivotedlatch, B having-a beveled end, which is adapted to be operated upon by a beveled stud, B", connected with amovable semicircular slide, B titted into an annular groove of the bed-plate A. (See Fig. l.) I Pins at or near the ends of the slide B enter slots in each of two elbow-levers, B having their fulcra on pins secured to the bedplate, the longer ends of the said levers being extended acrpss a groove, 13", made in the bed-plate A just within the groove which receives the slide B Each bobbin 0 will have a slot through its side wall and head to receive the end of the detecting-lever 0, shown as an elbow-lever pivoted on the support C for the bobbin, as in Fig. 2. Each lever C has pivoted upon its outerlower end a rod, 0 extended atits lower end through a hole in the yoke 0". Each rod 0 has a suitable spring, 0 to draw it down whenever the yarn on the bobbin fails to keep the broad or blade-like upper end of lever C in vertical position'wit-hin the slot made through the side of the bobbin. -The lever U is permitted to turnoutwardly only when the yarn upon the bobbin becomes exhausted. Thelever C, at the right of Fig. 2. is in the position it will occupy when not held up by the yarn, and the lower end of its rod 0 will in such condition be depressed into the groove B", so that the end of the said rod, during the rotation of the yoke 0 will strike the end of the lever B, then in its path, will move the said lever, and the latter will move its connected slide B causing the stud B to strike and tip the latch B and release the shipper to be moved by its spring 13.

The axis or fulcrum B for the belt-shipper has its bearing in a hanger, B.

The shait B has on its end a. worm, D, which engages a worm-wheel, D", on the shaft 1), having at its end a cam, D This cam actuates a lever, D pivoted at D, and having a pawl, D which engages a ratchet-wheel, l), on the shaft 1), which has secured to it the usual fluted roll 1", D between which and the pressure-roller D the knitted fabric is taken away from the machine.

The fabric, just at the rear of the rollers D D is acted upon by a roller, D carried by a yoke, I), having hung upon it a weight, I), to enable the roll D to exert the proper amount of tension on the work. The free end of this yoke is connected by rod D with the lower end of a lever. D pivoted at I)", the other end of the said lever being extended under the latch 13, before described.

The pawl D is permitted to engage and operate the ratchet I) only when the yoke l) hasbeen sufl'iciently lowered by reason of the production of knitted goods by the needles, the end ofthe said pawl then engaging the ratchet. The paul D when the said yoke is elevated and there is no: sufficient goods to be taken up by the rollers, is kept from engagement with the ratchet l) by a pin, 1). (see Fig. 49,) which projects from one side of the yoke l) and keeps the pawl lifted. When the work runs off the needles, the yoke 1) drops and turns the lever l) to lift the latch and stop the ma -hine, as belore described. Spring 1) counter-balances the weight of the rod D the lower hooked end of which (see Fig. 49) does pivoted lever, IE.

not hold up the yoke D when the machineis delivering work properly.

The shaft B has on it a large fast pulley, E, and a smaller fast pulley, E, each substantially twice as wide as the belt which it. moves.

Pulley E, by band E on the fast pulley E drives the main shaft E of the maehine at its fastest speed. Pulley E hasabelt,E ,which is extended about the loose pulley E on shaft E At the side of fast pulley E is a loose pul ley, E of like diameter, and at the side of loose pulley E is a clutch-pulley, E of same diameter, but recessed at one side (see Figs. 2 and 48) to fit a flange, E fast on the main shaft. The main shaft next the outer side of clutch-pulley E has loose on it agrooved hub, E embraced by the forked end of a The loose hub E has attached to it a pin, 2, which is made to project through a hole made in the side of the pulley E which pin, as the said hub is reciprocated on the sleeve G of the clutch-pulley E by the lever E", is withdrawn from the flange E within the pulley E, or is placed in a hole in the said flange. When the pin is engaged with the flange E the clutch-pulley E is clutched or made fast on the main shaft, and vice versa. When the machine is running at its highest speed, belt E is on the loose pulley E; but when the speed of the machine is to be reduced-as when changes are being made in the several operating-cams, to be de- SCI'ib6d-tl1eli the belt E is shipped from the loose pulley E upon the fast pulley E, and the-belt E lroin fast pulley E onto loose pulley E. Such change of belts causes the jacquard to be operated one step of its chain at each revolution oflheeam-plate, whereas when the belt is on the fast pulley E the said jacquard is turned but one step at each six revolutions of the cam-plate.

,The pattern-surface of the Jacquard mechanism is shown as two chains, F F, extended over sprocket-wheels on the shafts F F The lower looped ends of the chains are extended about like sprocket-wheels F carried by a yoke, F madeadjustable by a screw, F to thus keep the chains taut. Each chain contains pattern-bars, on which are projections for one-half the changes to be made, the chains operating alternately.

The shafts F and F have at their ends thothed gears F and F which in practice are engaged with each other. In Fig. 2 the gear F is shown broken out; bntthe line of its periphery is shown by dotted lines. The shaft F is driven positively, as presently described, and moves the other with it by-the gears referred to. The shaft F at its rear end. has a bevel-pinion, G, (shown in Figs. 38, 39, and 40.) which is engaged by a larger bevel-gear, G, on a shaft, G having tixed on ita ratchetwheel, 12. Loose on this sha't is a pawl-carrier, 6*, having a pawl, G, u hich engages the ratchet 12 and moves the shatt G intermittingly. {thisHiawl-carrier has a pin, 5, at its upper end, which supports two rolls or disks,-

3 4, to be operated upon respectively by the cam-wheels G G ,tl1eformer havingone throwpoint, (see Fig. 47 and dotted lines, Fig. 40,) while the latter has seven throw-points. The cam-'wheel G always acts against the roll 3 at each sixth rotation of the camplate of the machine; but the cam G when it is in position to strike the roll 4, actuates the pawl-carrier G and its pawl more frequently, as it is necessary to do when the pattern-chain is to be moved more frequently to effect the necessary changes for knitting, 850., (as will be described from time to time.) The cam G6 is fast on shaft G having at its outer end a worm-gear, G engaged and rotated by a worm, 7, on a short shaft, G having a bevel-gear, 8, which is engaged with and driven from a bevel-pinion, 9, fixed to the handwheel G, which latter, as shown in Fig. 48, is fixed upon the long cylindrical sleeve G of the clutch-pulley E before referred to.

The rolls of the pawl-carrier G are held againsttheiractuating-cams by aspiralspring, 80, and reverse movement of ratchet 12 is prevented by a detent, 13. When the clutch-pin 2 is withdrawn from the flange E by the forked lever B, as will be hereinafter described, anth the belt drives the clutch-pulley E then loose on the main shaft, the patternchain shaft will, through the shaft (3", be turned while the main shaft and knitting mechanism are at rest, at which time. and by which movement lam enabled to cause the jacquard to effect the shogging of the needle-cylinder, as will he hereinafter described.

The cam G loose on shaft G so as to be moved longitudinally thereon, is connected with and so as to move in unison with the shaft G and cam G by a pin, 14, (see Figs-.2 and 46.) extended from one side of cam G Cam G at its side, has liXi-d to it an annular-lygrooved hub, 15, which receives in its groove a forked arm, 16, loose on the sliding rod 17, provided with a lug, 18, which acts against the hub of arm 16 and moves it. positively to separate the cams G G The rod 17 has upon it a spring, 19, the operation of which will be described further on.

When cam G7 is in the position shown in Fig. 41 it is inoperative, or, rather, its periphe1 travels in the space between the two rolls 3 4, and does not actuate the pawl-carrier G but when it is moved away from the cam G -as when. the belts E and E are on the loose pulley E and the clutch-pulley E then fast with relation to the'main shaft by the pin 2 and flange E --then the cam Gr strikes the roll 4 and actuates the pawl-carrier G to movethepattern-shaftsinorefrequently. The rod 17 has fixed upon it an arm, H, provided with a roll, H against which bears a projection or lug, 88, of one of the pattern-bars t. (See Fig. 41.) \Vhen the lug 88 strikes the said roll H the rod 17 is moved positively in the direction of the arrow H (see Fig. 41,) and by the lever 11*, of the first order, moves the shipper-rod H in the direction opposite the rod 17, causing the pins on the said shipper-rod (shown in Fig. 2) to move the belts E and E upon the pulleys E and E, as indicated in Fig. 2, when the fast speed of the machine is again resumed. At the com mencement of the movement of rod 17 in the direction of arrow H the roll 4. rested on one of the projections of cam G", thereby producing sufficient friction between the said roll and cam to practically prevent the sliding of rod 17, provided the arm 16 was fast on the rod 17. In view of this fact, and to enable this rod 17 to be moved at the exact time required to effect the changes in the machine without unnecessary loss of time, I had to place the hub ofthe arm 16 on the rod 17 and provide the spring 19 to be compressed during the moveinentofthesaidrod. Assoonasthebeltsarrive in theposition Fig. 2, the cam Ghaving been turned far enough to let the roll 4 drop from its projections, the spring 19 operates to move the arm 16 and cam G quickly into the position Fig. 41.

The revolving cam-plate M is located in the open center of the bed A, and derives its movement of rotation from a bevel-pinion, M on the main shaft E, (see Fig. 3,) it engaging an annular series of teeth'at the under side of the said cam-plate, all as usual. The main shaft E, at its inner end, carries a bevel-gear. M which engages a series of teeth at the under side of a loose ring, M which has attached to it and projecting upward and inward two steel plates, M, (see Fig. 5,) which support the plate -needles which are being reciprocated. This is a common device.

The bed N for the cylinder or vertical needles 20 (shown clearly in Fig. 3) is supported at its lower end by a disk, N. loose on a spindle, N fast in the yoke 0 which is bolted to the upper side of the cam-plate M, so that the said spindle, as the yoke is revolved with the plate M, turns in the disk N, which rests on the collar N fast to the said spindle, the pressure between the disk N and lower end of the bed N being sufficient to preventdisk N from turning.

The cam-cylinder P for the vertical needles, it being substantially the same as in my application No. 15,024, hereinbefore referred to, and

IOC

IlO

fast upon the spindle N, has two annular grooves, N N, (shown clearly in Figs. 7, 8, and 10,) which receive the buits of the cylinder-needles. The camcylinder P has a switch (see Fig. 7) composed of a block, 21, having its lower end beveled, and a block, 22, having its upper end parallel with one wall-of the groove N and of a rod, 23, to which the said blocks 21 and 22 are attached. The said camcylinderhasalsoaknittingcam,Pflfordrawing doan the cylinder-needles 20, the said cam being connected with a rod, 24. YVhen the switch is in itslowest position, as represented in full lines, Fig. 7, the butts of the needles will be diverted from the upper groove, N into the lower groove, N to enable cuffwork to be knit. This switch, in operation, has three positions, two of which are designated in Fig. 7 by'dotted lines. The switch will occupyits second or next highest position (shown by (lotted lines) when the separating course of yarn of plain knit-work is being knitted, the cylinder-needles then descending from the upper into the said lower groove; but the cylinderneedles are drawn down only so far by the lower end of block 21 as to enable the yarn supplied to the plate-needle-yarn carrier 25 to the cylinder-needles are not supplied with yarn.

The switch of the cam-cylinder occupies this second position, however, for but a single rotation of the cam-cylinder, and the single course knitted at such time by the plate-needles with its regular thread will be subsequently cut and drawn out to separate the fabric knitted when the switch was previously in its lowest position from the fabric knitted when the switch occupiedits highest position. When the said switch is in its highest position, the upper end of block 22 will close the gap in the lower wall of groove N and when being lifted from its lowest full-line position into its highest position, as shown in dotted lines, the upper end of the block 22 will act to lift the butts of all needles then above it into the line of the groove F and so long as the switch occupies its highest position the .butts of the needles 20 will travel in the upper groove, and will not be reciprocated by the switch, but will be raised and lowered by the usual knitting-cams, P and P Theswitch will be in its highest position when cardigan or half-cardigan work is being knitted, the vertical needles at such times being kept elevated while opposite the plate-needle-yarn guide, that the plate-needles 27 may draw the yarn of the plate-needle-yarn guide about the shanks of the cylinder-needles below their latches; but these cylinder-needles employed in knitting cardigan or half-cardigan work will have yarn introduced into their hooks by their own yarn-guide before their butts are acted upon by the drawing-down cam P so that as the cylinder-needles come into the groove N the plate-needle yarn about the shanks of the cylinder-needles below their latches will close the said latches and imprison in the hooks of the cylinder-needles the loops of yarn supplied thereto by the cylinder-needleyarn guide, the said loops ofplate-needle yarn being cast off over the tops of the cylinderneedles. The cam-plate M (see Fig. 11) has at its under side a drawing-in cam, 29, an auxiliary throwing-out earn, 30, and two pivoted throwing-out cams, 31 132, substantially such as in my application herein referred to.

The switch-cams 31 132, when they are in action, divert the butts of the plate-needles from the groove 33 into the groove 34. As shown in Fig. 11 in full lines, all the said cams are in position to permit the needlecylinder to be shogged the distance of one needle, as described in my application referred to.

If it is desired to knit cuff-work or halfoardigan work, the switch-cam 31 and auxiliary throwing-out cam 30 will be putinto their dotted-line positions, and if it is then desired to knit full cardigan the switch-cam 132 will be put into its dotted-line position. The auxiliary throwing-out cam 30 occupies its fullline position only when the cylinder is to be shogged, it being placed in such position be-.

fore shogging the cylinder to enable the butts of the plate-needles in advance of it to remain in the groove 33 of greatest diameter, which keeps the plate-needles drawn in, and imme diately after shogging the cylinder the auxiliary throwing-out cam will be moved into its dotted-line position, throwing out bodily the butts of the needles then in front of it, which enables them to have yarn supplied to their books by the plate-needle-yarn guide 25 before the butts of the said needles are acted upon by the drawing-in or knitting cam 29. Alter the cam 30 is moved into its dotted-line position, but before the cam-plate M completes its rotation, the switch-cam 31 will be moved into its dotted-line position to throw out the plate-needles just before they arrive at the latch-opening portion of the plate-needle-yarn guide 25,in order that the latches of the plateneedles maybe properly opened for the reception of yarn therefrom.

Eachof the cams and switch -cam of the cam-plate, and the switch and cam of the camcylinder, are in this my invention to be shifted automatically. Each of these cams and switchcams and the switch has connected with it a slide-bar, which will be moved at the proper times, as 1 will now proceed to describe, by cams which I shall denominate Jacquard cams, for the reason that they are put into one or the other of their operative positions through the instrumentality of the pattern surlace or chains referred to.

The stationary bed A (shown in top view, Fig. 1, and partially in Figs. 20 and 21) has,it will be noticed, a series of concentric grooves, which receive a series of arc-shaped slides, a b c d 6, having, respectively, legs a b c" d 6. (See Fig. 38.) The slide a, at one end, has a diagonal slot, a (see Fig. 30, and in dotted lines, Fig. 29,) which receives a roller-pin, a, projected downward from the sliding block 0,, having attached to its upper side by screws the two cams a a. The block a is titted between guides at of aplate attached to the bed A by screws a The cams a a are employed to shift the drawing-in or knitting cam 29 of the cam-plate. The cam 29 has at its upper side a screwstud, a extended up through a slot in the cam-plate M, as shown in Fig. 29. The stud a is engaged by one end of the elbow-lever a the long arm of which is made to enter a transverse slot in the under side of the slide rod a", (see Fig. 31,) fitted into a guide-box, a, secured upon the top of the cam-plate M. The slide-bar a at its outer end, has a rollerslud, a, which strikes against one or the other of the cams a a when placed in the path of movement of the said roller-stud by the pat tern-surface. When the slide-rod a is in the position represented in full lines, Figs. 29 and 31, the knitting-cam 29 will occupy its dotted-line position, Fig. 11, and the plateneedles will be drawn to produce the maximum length of stitch; but when the said cam 29 is as in full lines, Fig. 11, the slide-rod a will be in the position shown by dotted lines, Fig. 29, and full lines, Fig. 1.

If it is desired to change the position of the sliding block a so as to move the cam 29 into its full-line position, Fig. 11, to draw a short loop, one of the projections, a near the end of one of the bars tof the pattern-chain F, will strike the leg at and push the arc-shaped slide a in the direction of the arrow a Fig. 1,'-

far enough to move the sliding block a and place the cams a and a into the dotted-line position, Fig. 29, so that. during the rotation of the cam-plate the roller-stud a on the sliderod (0 it then occupyingthe full-line position, will strike the cam aflwhich will at once draw the said slide-rod into its dotted-line position and place cam 29 in its full-line position. The cams (t and a will remain in this dotted-line position until the cam 29 is to be again changed, the roller-stud moving freely through the open space between the said cams, and the sliderod (L Wl1l(3l],lh will be noticed, is toothed at its upper side, as at a"will be held in place by one of the slide-rod locking catches or springs e or a, the ends of which arehooked to enter the spaces or notches between the said teeth. W'hen the bent or hooked end of one of the said catches enters one ofthe said notches, the bent or hooked end of the other of said catches will rest upon the top of a tooth next to the notch then entered by one catch.

By the employment of the two catehes-one to enter a notch and the other to rest upon a tooth, as described-I am enabled to make finer adjustments than by the employment of but one spring.

The slide-rod a, at its front side, has attached to it by screws a a. catch-lifting slide, a,provided ith a roll, a, which, when the catches a and a) are to be lifted to permit the sliderod a to be shifted, will first strike against that one oi the cams a a then in operative position,which will move the catch-lifting slide a longitudinally on the slide-rode before the roller-stud a." of the said slide-rod strikes the said cam. The movement 01 the said catch-lifting slide in advance causes one or the other of the inclines on it (shown in Fig. 32) to act upon one or the other of the inclined edges of a finger, a, which rests in a depression of the said lifting-slide between its inclined edges, and causes one or the other of the said edges to lift the finger, so that it, acting against the under side ofcatch a. a" lifts that one of them which is then engaged with a notched part of slide rod a", lea ing the said slide-rod free to be moved longitudinallv as soon as the roller it strikes the cam (PM a which is then in operative position. When the roller-stud a of the sliderod a reaches a position between the two parallel walls of the two cams a a, (the roller a 'ot' the lifting-slide a having been held from longitudinal movement by the parallel walls of the cams a a. while the slide was being moved longitudinally,) it will be observed that the relative longitudinal positions of the sliderod and the catch-lifting slide will have been changed sufliciently to again bring the notched part of the lifting-slide directly under the tinger, so that it is permitted to fall, and with it the catches above it, that one of the catches which was upon the top ofa tooth then dropping into anotch between the said tooth and the one next to it.

Each of the slide-rods herein employed will have one or two locking-catches such as described, and a catch-lifting slide to disengage it from the toothed part of the slide-rod, with which it is adapted to co-operate; so I will not herein further describe such devices; nor do I consider it necessary to letter the said parts in the other figures.

WVhen the slide-block a is to be moved to move the cams a a from their dotted to their full line position, Fig. 29, the leg at of the arc shaped slide a will be acted upon by asuitable projection, 35, of the chain F.

Each projection a or 35, to effect the change of length of loop, as described, will be made adjustable on the barstof the chains by means of set-screws 36, so thatthe arc-shaped slide may be moved more or less, and so place the cams a or a that more or less of their inclined faces may operate to move the sliderod more or less, according to the distance it is desired to move the drawing-in cam 29.

The auxiliary throwing-out cam 30 hasa screw pin or stud, I), (see Fig. 27,) which is passed up through a slot, D in the cam-plate M, and into a slide-rod, I), held in a guidebox, D The said slide-rod at its onterend, has a roller-stud, b, which acts to draw the slide-rod boutward and place the auxiliary throwing-out cam 30 in its full-line position preparatory to shogging the needle-cylinder N. The roller-stud 1) acts against one edge of the cam-link 81 when the latter is in the position shown in Fig. 21 and in dotted lines, Fig. 22. As soon as the roller-stud b, it having passed beyond the cam-link 81, reaches a position opposite the cam b", it occupying the.

which, as described of arc-shaped slide a, has able projections arranged upon the bars t of near its end a diagonal or cam slot, (shown in dotted lines, Fig. 28,) to receive a downwardly extended roller-pin, 33, carried by the slideblock 32. The arc-shaped slide d will have its leg (1 acted upon at opposite edges in the proper order by suitable projections on theface of the pattern-chains F F.

The switch before described as forming part of the cam-cylinder P (fully shown in Fig.7) is automaticallyoperated by the slide-rod 0 held in the guide-box b at the side of the slide-rod b. The slide-rod 0 at its inner end, has a diagonal slot, 0 into which is entered the roller-stud c of a clamp-block, c securely clamped upon the rod 23 of the said switch. The slide-rod 0 at its outer end, has a roller-stud, cflwhich, during the rotation ofthc cam-plate M, will act upon the edges of the cam-links 0 c whichever link may be. placedin operative position in accordance with the projections of the pattern-chains. When the slide-rod c is in the position shown in Figs. 1, 25, and 26, the switch will be in its highest dotted-line position, Fig. 7, to enable the machine to knit cardigan or halfcardigan, as before described. It the said switch is to remain in its highest position, the cam-links c" 0 will remain as shown in lull lines, Figs. 1 and 25, and the roller-stud 0 will pass freely between the cam-links 0 0 but ifthe said switch is to be lowered one step, as u hen introducing the separating course of yarn taken from the plate-needle-lhread guide, the cam-links c 0 will be turned into the dotted-line positions, Fig. 25, betore the roller stud 0 reaches them, so that the said stud will strike one edge of the cam-link 0 The switch will ordinarily be held in its intermediate position last referred to for but one course, when the cam-links c 0 will be put into their full-line positions, Fig. 28, so that the roller-stud 0 during the next revolution of the cam-plate M, willstrike the edge of the cam-link c, it then being placed at agreater angle than in dotted lines, Fig. 25, which will cause the slide-rod to be moved yet farther inward toward the center of the camplate, to put the switch into its lowest or full line position, Fig. 7, to enable the machine to knit cuff-work or one-and-one-rib work with the plate-needles and the yarn of the platencedle-yarn guide,the said piate-needlesdrawing the said yarn about and into the books of the cylinder-neetilles, as usual.

Each cam-link c and c at one end is pivoted to a. slide-block, c", in line with the slide-block 32, both of which blocks are titted to slide in the same guides, The other ends of the cam-links 0 c are slotted, as shown in Figs. 25 and 28, to fit over stationary pins 36 37, fixed to the guide The slide-block c has at its under side a roller-stud, (shown in dotted lines, Fig. 23,) which enters a diagonal slot, also therein shown in dotted lilies, made in the arc-shaped slide 0, the leg e of which is acted upon at one or the other 01 its edges, or roll thereon, by suitthe two pattern-chains F F.

The switch-cam 31, (see Fig. 11,) which, when in its temporary full-line position, re-

tains the butts of the plate-needles in the groove 33 of greatest diameter, the auxiliary cam 30 then occupying its full-line position, Fig. 11, has a stud or screw, 33, which is extended up through a slot in the cam-plate M, as shown in Fig. 22, where it is engaged by a lever, 39, the other end of which, extended through an peningat one side of the guidebox 40, enters a recess formed at the lower side of the slide-rod d the said recess being snfficiently large to admit of lost motion, as will be described.

The slide-rod d has a roller-stud, d, which, when the switch-cam 31 is in its dotted-line position-the machine then knitting regularly, and the auxiliary throwingoutcam being in its dotted-line position, Fig. 1l-.will pass freely between and not be actuated by the cam-links 8L and 4-1. \Vhen the slide-rod d is in its lull-line position, Fig. 22, and the switch-cam 31 is in its dotted-line position, ifit is desired to then place the said switch-cam temporarily in its full-line position, Fig. 11, the slide-block d fitted into guides d will be moved by the arc-shaped slide 0?, it having a suitable diagonal slot, (shown in Fig. 22,) which acts on a roller-stud at the under side of the said block 11, to place the cam-links 81 41 in their positions shown by dotted lines, Fig. 22, and full lines, Fig. 21, when the roller-stud d will strike the edge of the cam-link 81, which, acting as a cam, will draw the slide-bar d outward into its dotted-line position, Fig. 22, where it will remain for one revolution of the cam-plate M, when the roller-stnd (1 will strike the edge of cam-link 41, which. during each one revolution, or nearly so, of the cam-plate M, has been changed from its dotted to its full line position, Fig. 22.

The knitting-cam P of the cam cylinder (fully shown in Fig. 8) has a rod, 24, which is embraced by a clamp, 42, (see Figs. 34 and 35,) having a roller-stud, 43, w hich is entered into a slot, 41, at the end of the slide-rod f, fitted into the guide-box f, secured to cam-plate M. The outer end of slide-rod f is provided with a roller-stud,f such as common to the other slide-rods, which at proper times strikes one or the other of the cams f f or passes freely between them it the cam P is not to be raised or lowered. With the slide-rod f in its fullline position, Fig. 34, the cam P will occupy its full-line position, Fig. 8, t0 thus draw loops ot'greatest length, and so long as thecamsfif occupy their full-line position, Fig. 34, said slide-rod will not be changed.

It it is desired to draw shorter loops of yarn by means of the cylinder-needles. the camsf f will be moved into their dotted-line positions, Fig. 34, when the roller-stud at the end otthe slide-rod fwill strike the cam f which will move the slide-rodf outward into its dottedtop line position. These camsf f are secured to a cam-block, f fitted into guides f, secured to the bed A. The block f will have at its under side a suitable roller-stud to enter a diagonal slot in the arc-shaped slide 1), the said stud and slot being represented in dotted lines, Fig. 34. The leg I) of slide b, or the roll at its lower end, will be struck at the proper times by suitable projections of the pattern-chains F F, so as to move the said arc-shaped slide positively in either of its two directions, and the said projections of the said pattern-chains, as described ot' the projections a and 35, will preferably be made adjustable, so that the cams f and f may occupy any desired intermediate positions between their full and dotted line positions shown in Fig. 34.

The loops of yarn drawn by the cylinderneedles from the cyliuder-needle-yarn guide will be lengthened automatically when changing from cuff to cardigan or halt-cardigan. Heretotore when it has been desired to separate two knitted tubular articles made in succession, one of which is to present a finished end, it has been customary to introduce one or more courses of a different thread, usually asmooth cotton thread temporarily tied on the regular yarn, which cotton thread was thereafter withdrawn.

I have discovered that tubular' ribbed knitted fabrics will not unravel on the machine, provided the last or next to the last terminating course of the fabric is knitted with the cardigan or half-cardigan stitchtwo yarns being then used-and thatthe loops formed from the yarn taken by the cylinder-needles from the cyllnder-needle-yarn guide brought into operation for cardigan-work be drawn by the said cylinder-needles to produce acourse of long loops, or loops of an extreme length; and that, to separate the terminating end of said fabric from the fabric next to be commenced and ended on the machine,l need not introduceaseparatecotton thread,asheretoforedrut may introduce instead one course of thread from the regular Yktl'll of the plate-needlethread guide, the said course being, however, knitted entirely by the plate-needles, the cylinder-needles then acting as sinkers, as before described, and forming one course of plain web such would be produced in a circular-knitting machine containing but one set ot'needles.

The switch-cam I33 (see Fig. 11) has a pin, 46, which is extended up through a slot in the cam plate M, as in Fig. 37, and into a hole in a slide-rod, g, which latter, fitted into a guidebox, g, attarhed to the plate M, has a rollerstnd, 9 which, as the cam-plate M is rotated, causes the said roller-stud to strike one or the other of two cams, g 9, attached to a camblock, g titted into the guide 9 or enables the said roller to pass bet ween the said camst'reely. When the switch-cam 132 is in its full-line position, Fig. 11, the machine then knitting haltcardigan or one-and-one rib work, the sliderod 9 will occupy the full-linc position, Fig.

36 but when the said switch is in its dottedline position the slide-rod y will be as in full lines, Fig. 1, and as in dotted lines 36. To change the switch 132-from its full to its dotted line position to knit cardigan-work, the cams g y will be moved into their dotted-line positions, Fig. 36, so that the roller-stud y will strike the cam 9 which will draw the slide-rod g outward into the dotted-line position, Fig. 36, or into the full-line position, Fig. 1. Subsequent movement of the cams g 9 back into the full-line position, Fig. 36, will effect the movement of the slide-rod g in the opposite direction,or back into its full-line position, Fig. 36.

The slide-block g? has at its under side a pin which enters a diagonal slot (see dotted lines, Fig. 36) made in the arc-shaped slide 0. having a leg, 0, provided with a truck or roll which is acted upon at the desired times by suitable projections on the pattern-chains F F,'according to tbe direction it is desired to move the said slide 0 or the slide-block 9 Having knitted the one plain course referred to with the regular yarn taken from the plateneedle-yatn guide, the next course in succes sion will enter into and form part of the next article to be knitted, which will be supposed to be a cuff knitted with the rib-stitch, both sets of needles being then emplo ed, the yarn being delivered from the plate-needle yarn guide. To so manipulate this course, as described in my application referred to, thatthe commencing course shall serve as a finish for the end of the cut't'joined' with the separating course and obviate hand finishing, I shog the needle-cylinder to the right or left the distance of one needle. This is done at the end of the first course after the introduction of the separating course referred to, andthc second and other succeeding courses of the cuff will be knitted with the cylintL-r needles in their shogged positions; or, it it is desired to produce a series of crossed loops to serve as an ornamental border, the needle-cylinder may be shogged in the opposite direction at the end ol'one or more courses. By cu tting-the separating course the cuff just referred to may be separated from the article previously knitted, and with which it is joined by the separating course.

The cylinderNhasatopposite sides two dogs, 47 48, which are embraced by the forks 49, secured by bolts 50 upon the ring 5l, titted into an annular recess at the under side of the bed M for the plate-needles, (see Fig. 3.) the said ring 51 being retained in its recess by buttons m The ring has connected with it an arm, 5'1, (shown best in Fig. 35,) having a roll, 53. (See Fig. 39, where the arm 52 is shown in section.) The roll 53 is placed between the peripheries of the two cylinder-shogging cams 51L 55. (See Fig. 39 and separately in Figs. 4* and 45, which latter figures show the opposite sides and edge of the said cams.) The peripheries of these cams act against the roll ICC IlO

53 and move the arm and needle-cylinder N in one or the other direction, as may be desired. These cams 54 and 55 are held loosely on the shafts F F of the sprocket-wheels by which the chains F F are suspended and moved.

Each cam 54 and 55, at its rear side, is provided with two dogs having square ends, and secured to the cams so that they will be in the path of movement of the projecting-ends 53 of some of the bars of the pattern-chains, (see Fig. 38,) so that the ends 58 of said bars will, at the proper times. strike the dogs and turn the said cams intermittingly for half a revolution, the part of greatest radius of one of the said cams being always opposite a part of the other cam of least radius, so that the two cams by their joint operation will hold the roller 53 steadily, moving the needle-cylinder positively in either direction, and holding it in place against accidental movement. The cam 5* has two side inclines, 58 59, and the cam 55 has two lifting-cams, 6U 61. The earns 54 and 55, as shown in Fig. 39, are in the position they will occupy when the machine is knitting regularly, the cam-plate then rotating.

As described in the early part of this specification, the knitting mechanism must be entirely stopped while the needle-cylinder is being shogged; but at such time the motion of the Jacquard chain is continued. To effect this the machine is provided with a rock-shaft, 62, (see Fig. 39,) having two arms, 63 and 64. The arm 63, at'its outer end, is connected with a pin 65, which is projected up through a hole in the bed A by the spring 66 (see Figs. 38

.and 39) justbefore or as the stop J, (see Fig.

11,) connected with the under side of the camplate M, reaches a position in the movement of the said cam-plate near the hole above the said pin 65. The pin 65 having been thrown up, as described, its upper end is struck by the end of the stop J,connected with the cam-plate M, and the further rotation of the cam-plate is arrested. In Fig. 53, I have shown this stop in dotted linesas just to strike against the pin 65. The dotted lines, Fig. 53, also show the positions of some of the other parts of the machinejust as the stop and pin are to strike. The spring 66 assumes control of the rockshaft as soon as the end of its arm (it arrives at the end of the cam 60. \Vhile the cam 55 is being rotated one of the side cams, 58 or 59, of the cam 54it being rotated at the same speed as cam 55-acts against the inclined end of the plunger n, held in the bearing n The front end of the plunger 12 is slotted to receive loosely the wedge n, the opposite end of which is inserted in a slot made in the end of a short pin, 67, held in the yoke 69 and pressed outward by the spring 68. The upper edge of the wedge a when pushed toward the right in Fig. 38, acts upon the lower end of and lifts the pin a The stop J (see Figs. 38 and 12) is inclined, so that as the forward end of the said stop comes in contact with the upper end of the elevated pin a it will depress the same, the wedge 11. then descending with it. owing to its peculiar connection with the plunger 'n, and the inner edge of the said wedge, by its action against the upper end of the pin W-which, at its lower end, rests upon one arm of the bellcrank lever n -turns the said bell-crank lever and moves horizontally the rod a which, at its other end, is joined with the lever E", which em braces the collar E and by the movement of the said collar disconnects the clutchpulley E from the flange E tixed'to the main shaft. Just as the pin 2 of the co lar is withdrawn from the flange E the front end of the stop J arrives against the pin 65, before referred to, and the knitting parts of the machine are instantly stopped; but the clutch-pulley E continues to revolve, as the belt E is then on it, and, as described in the early part of this specification, the motion of the patternchains is continued. The continued rotation of the earns 55 and 54 carries the cam 6t into position to strike the rear end of arm 6% of the rock-shaft 63, causing the arm 63 to pull down the pin 65awayt'rom thestopJ, and at the same time,orsubstantially so,thesidecam,59,passes the end of the plunger n, permitting the spring 68 to act to push the wedge 12 and plunger it toward the left in Fig. 38, which permits the spring 10 (see Fig. 2) to operate the rod n and lever E to actuate the collar and pin 2 for the latter to engage the flange E when the rotation of the main shaft will be again resumed.

The latch-opener for the cylinder-needles is 5. It operates as usual.

When one-and-one-rib knitting for a cuff is to follow cardigan or half-cardigan work, the one-and-oneknittingemployingbutonethread, while in cardigan and halfcardigan two threads are used, as described, the yarn supplied by the cylinder-needle-yarn guide to the.

books of the cylinder-needles must be cut off between the said yarn-guide and the fabric just after the cylinder-needles are lowered by the passage of their butts down through the switch into the groove N when theyceaseto be supplied by yarn from the cylinder-needleyarn guide. By drawing down the'cylinderneedles in this way their books are enabled to pass below the cylinder-needle-yarn guide.

The yarn from the cylinder-needle-yarn guide is drawn by the revolution of the cam-plate M directly between the blades of a threadcutter, 8 (see Fig. 15,) and the end of the yarn next the yarn-guide is held between the forked spring 8 at the rear side of the rod s,w1th which the cutter is attached. As soon as the cylinder-needles .are again worked regularly and the switch is in its highest position, the cylinder-needles, in their descent, catch the yarn of the cylinder-needle yarn guide, it being then held by the spring 8 and knitting will be resumed by the cylinder-needles with the said yarn.

lettered r, and is shown clearly in Figs. 14 and The key 70, Figs. 13 and 11, permits the introduction and removal of the plate-needles, and the key 71, Figs. 19 and 5, permits the in troduction and removal of the cylinder-needles.

The usual support, 73, for the plate-needles, connected with the shank 74, is shown in Figs. 18 and 5. I

The edges of the links 81, 41, c and 0 form cams or inclines, and I therefore denominate them cam-links. I prefer these cam-lin ks to stationary cams such, for instance, as f and f -t'or the reason that they occupy less space.

Insteadoftheparticularpattern-surfaceherein employed, I may use any other well-known form of pattern-surface, and by change of the projections of the pattern-surface I may control the movement of the various cams and the times of shogging the needle-cylinder according to the class of Work being done.

w The take-up mechanism is operated by the counter or power-driven shaft B, the pulleys on which drive the main shaft and the knitting devices, which enables the strain on the main shaft to be maintained more nearlyeqnal than were the take-up devices driven by the main shaft, as heretofore.
